Transforming Home Comfort with Cutting-Edge Technology
At AirGreen, we take pride in delivering modern, reliable, and energy-efficient HVAC solutions that meet the diverse needs of homeowners in Blainville and the surrounding regions of Montreal, Laval, Longueuil, South Shore, and North Shore. Recently, we completed the installation of a SHARP BU Double Zone Heat Pump, an advanced unit known for its outstanding efficiency, performance in cold climates, and unique features like Plasmacluster technology.
The Project: Delivering Comfort for Every Season
When the homeowners in Blainville reached out to us, they had a clear objective: improve year-round comfort while maximizing energy savings. After evaluating their requirements, we recommended the SHARP BU Double Zone Heat Pump, a 24,000 BTU system with two indoor units, each offering 12,000 BTU. This setup was ideal for their home layout, providing precise climate control across two distinct zones.
What Made This Installation Unique?
- The Home Layout: The house had a unique split-level design that required a strategic approach to positioning the outdoor unit and routing the piping.
- Aesthetic and Practical Considerations: The external compressor had to be installed securely without compromising the home’s visual appeal, while the piping was concealed for a clean, professional finish.
- Optimal Placement: Both indoor units were carefully placed in rooms where they could deliver maximum airflow while operating quietly.
The SHARP BU Heat Pump: A Smart Choice for Homeowners
Advanced Features That Stand Out
The SHARP BU Double Zone Heat Pump isn’t just any HVAC system—it’s an investment in comfort, efficiency, and air quality. Here are the highlights of what makes this model a favorite among homeowners:
-
Outstanding Heating and Cooling Capacity
With a 24,000 BTU compressor and two 12,000 BTU indoor units, this heat pump ensures consistent heating in winter and cooling in summer, no matter the conditions. -
Performance at Extreme Temperatures
Designed to withstand harsh Canadian winters, the SHARP BU provides reliable heating down to -27°C. Even in the depths of winter, this system delivers uncompromising performance. -
Whisper-Quiet Operation
The exterior unit operates at a low 50 dB(A), making it one of the quietest models in its category. Inside, the two zones maintain an equally peaceful ambiance. -
Smart Energy Efficiency
With a 24.0 SEER rating, this unit achieves excellent energy efficiency, reducing energy costs while keeping the home comfortable year-round.
Plasmacluster Technology: Clean Air at Its Best
One of the standout features of the SHARP BU Double Zone Heat Pump is its Plasmacluster technology, a patented air purification system. This innovative feature actively removes pollutants, allergens, and odors from the air, ensuring healthier indoor air quality.
- Reduces Viruses and Bacteria: The system neutralizes airborne pathogens, contributing to a safer and healthier environment.
- Eliminates Allergens: Ideal for families with asthma or allergy sufferers, it reduces pollen, dust mites, and mold spores.
- Neutralizes Odors: Whether it’s lingering cooking smells or household odors, Plasmacluster ions keep the air consistently fresh.
Why Choose the SHARP BU for Your Home?
The Benefits in a Nutshell
- Two Independent Zones: Each zone can be controlled independently, offering tailored comfort for different areas of your home.
- Low Environmental Impact: The system uses R-32 refrigerant, an environmentally friendly gas with a lower Global Warming Potential (GWP).
- Extended Warranty: With a 10-year warranty on the compressor, parts, and labor, this system offers peace of mind for years to come.
- WiFi Integration: Manage your comfort from anywhere with integrated WiFi controls, making it easy to adjust temperatures on the go.
How the Installation Process Unfolded
For this project in Blainville, our team followed a meticulous process to ensure the highest level of craftsmanship:
-
Site Preparation
We assessed the exterior and interior spaces to determine the optimal positioning of the outdoor unit and the two indoor units. The homeowners wanted the setup to blend seamlessly with their home’s aesthetic. -
Outdoor Unit Installation
The 24,000 BTU exterior unit was mounted securely on a bracketed stand to protect it from snow accumulation and ensure proper airflow. Its compact dimensions—33.47 x 13 x 27.94 inches—allowed for a discreet yet highly efficient placement. -
Routing and Piping
Clean and concealed piping was a priority. Our technicians carefully routed the refrigerant lines and electrical connections along the exterior wall, ensuring a sleek, professional finish. -
Indoor Units Placement
The two 12,000 BTU indoor units were installed in key areas where airflow would optimize comfort. Each unit’s modern design complemented the interior spaces. -
System Testing and Customer Education
Once the system was installed, we rigorously tested its performance and ensured everything was running flawlessly. We also walked the homeowners through the features, including WiFi controls and Plasmacluster settings.

The job tools
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):
Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.
Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
